HARNESS-PAD MACHINE.

SPECIFICATION forming part of Letters Patent No. 284,696, dated September 11, 1883. Application filed September :25, 1882. f (No model.)

To all whom, it may concern:

Be it known that I, RICHARD J. WELLEs, a

. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Harness-Pad Machines, of which the following is a specication.

This invention relates to improvements in devices for holding the pad during that part of their manufacture known as the tacking operation,7 and is designed tov expedite and render easy and more perfect that part of the work.

The invention consists of the novel construction and combination of devices, as hereinafter set forth. Y

In the accompanying drawings, Figure lis a side view of my invention, partly in section. Fig. 2 is a front view thereof upon a reduced scale. Fig. 3 shows the sectional male form used to fill the pad during the tacking. Fig. 4 is a perspective of the same form, the parts being closed together, instead of being drawn out as in Fig. 3. Fig-5 is a cross-section upon the line 5 5 of Fig. l. Fig. (ishows an implement which is used after the withdrawal of the sectional form.

A represents a standard of suitable height to bring the work to a point convenient for the operator. Abed-piece, A', of metal, is fastened to the top of the standard, and upon this is secured a revoluble frame, B, upon which is laid a female form, C. The frame is secured to the bed-piece by a central pivot, b, and the form is removably held upon said frame by the pins c, which enter corresponding recesses in the frame. The form C, upon its interior surface, conforms to the shape, size, and outline desired for the completed pad, and after it has been placed in position the crimped cover D of the pad is placed therein. There is then placed within the crimped cover D, upon each side, a male form corresponding to the exact shape ot the female form, and intended to hold the parts in shape until the completion of the tacking operation. This male form E is made in three longitudinal sections or leaves, sliding and lying one upon the other, very much as do the leaves of a carriage-spring. These leaves are rounded upon one surface at the ends, so that when closed that surface appears asin Fig. et. The other surface is shown in Fig. 3, where the form is extended, and in this view are shown the slots e and catches e', by which the parts are held together and rendered capable of opening and closing. One of the leaves is provided with a handle, c?, by which the form may be drawn out of the pad after the packinghas been done. The burr-piece F is then placed in position, and itand the cover are then clamped firmly down by the pivoted arm G, setting down upon the center or check-hook screw, as clearly illustrated,'said pivoted arm being caused to do this by the operator through the foot-lever G and connecting-spring g and link g', and is held in the clamping position by engagement of the foot-lever with the ratchet g2 up on the standard A. When this has been donc, the pad is ready for tacking, and that operation is done first upon 011e side or half of the pad, and then, by turning the frame around,upon the other half.

those at the extreme lower end of the pad, the male leaved form is withdrawn bytaking hold of the handle ci, the leaves or sections coming out 011e at a time, and each drawing the next one in order after it, so that the thickness .of the form when thus extended does not prevent its passing through the thin end of the pad. The driving of the last tack or two upon each side is performed by the aid of a fiat piece of metal, H. (Shown in Fig. 6.) The frame and form are shown in Fig. 2 at right angles to the position occupied in Fig. 1. After the tacking is done, the pad is lifted off and the operation repeated with another one. XVhen it is desired to change the size or shape of the pad. it is only necessary to use other female and male forms. The clamping-arm is pivoted at m to a casting, n, secured to astationary bench, o, and when released from the ratchet the arm by the spring s, secured toit and to said casting or bench. By the use of the male forms in this manner, the operator is enabled to draw the leather as tightly as possible and with uniformity, and to make the pad alike on both sides and symmetrical throughout.

It will be noticed that the point at which the form is clamped lies in line with the axis upon which the form turnsthat is to say, the check-hook screw and the pivot of the frame are in the same vertical line. the turning of the form, so that the operator After all the tacks have been driven except This permits is propelled upward, so as to release the form ICO can work on both sides thereof without releasing the clamp, and this feature of the invention may be employed where the form is adapted to hold but one-half of the pad at a time, by mounting such form upon a pivot directly under the terret-screw, and causing the clamping-arm to act upon that screw instead of upon the check-hook screw. The sliding leaved male form may also be used with this modified form of the apparatus with the same benefit as in the apparatus shown in the drawings. l prefer, however, to use a form which will`support the entire pad, as I thereby economize time and labor.

I claim- 1. A double female form for holding Aboth sides ofthe pad whilebeing tacked, corresponding in size, shape, and outline to the size, shape, and outline desired for the pad, and mounted upon 4a support pivoted centrally under the bridge of the pad, in combination with such support,wherebyboth sides of the pad may be tacked without changing its position in the form, substantially as specied.

2. An apparatus for holding the pad while being tacked, composed of the female form, the

support for the form, pivoted centrally under thesame, and the male form for keeping the pad-cushion distended, all combined and operating substantially as described.

3. An apparatus for holding the pad while v being tacked, composed of a female form, a support for said form, pivoted centrally thereunder, and a pivotal clamping device which permits the form to be rotated with its sup` port, substantially as specified.

4t. An apparatus for holding the pad while being` tacked,'composed of a female form, a support for said form, pivoted centrally thereunder, and a clamping device acting upon the pad at a point in line with the axis upon which the form rotates, substantially as specified.

5. The' combi-nation, with a female holder, of a male form conforming thereto, and composed of horizontal leaves or layers attached one to another, substantially as specified, whereby said male form is permitted to be withdrawn from the pad as a unit.
